It is no secret that there is a strong bias in science against reporting negative results. While there is much to learn from success, the greatest discoveries often stem from failures. The communication of negative results and artifacts is critical for accelerating scientific progress, yet the current publishing environment rarely rewards such efforts. Whether its rejection by an editor or relegation to the back of the poster hall, scientists have been conditioned to avoid reporting what doesn't work. This symposium is designed as an open, honest, and judgement-free forum for presenting artifacts, mistakes, mishaps, and null results.

PHYSICAL SCIENCES SYMPOSIA

P01 - Revealing the Working Morphology of Energy Materials and Its Impact on Performance

To address material challenges in energy conversion and storage technologies, we need insights into the functional morphology of materials under reaction conditions. This symposium focuses on research using cryo-, in-situ, or operando microscopy to capture changes in the structure and chemistry of energy materials during operation in a time-resolved manner and experimental approaches for relating these observations to their impact on bulk properties.

P02 - Atomically Precise Manipulation of Materials

Atomically precise manipulation was first achieved with scanning probe microscopies, which continue to produce important advances using surface atoms and vacancies. However, recent developments in scanning transmission electron microscopy (STEM) instrumentation have made it possible to focus electron beams with sub-atomic precision, opening up new possibilities for manipulating strongly bound materials, including in the bulk. At the same time, other charged particle beams, including helium ion microscopy, have been added to the scientific arsenal, and advances in atomistic modeling and theory have elucidated new details of the beam-matter interaction, helping guide experiments. These breakthroughs have led to a series of studies on the controlled structuring, etching, deposition, phase change, and ultimately manipulation of individual atoms. This symposium will gather leading experts from this new frontier of materials science, including advances in machine learning and artificial intelligence, with a focus on atomic-level control.

P03 - Theory and Applications of Advanced Electron Tomography

Transmission electron microscopy (TEM) and scanning TEM (STEM) reveal the structure of materials across the nano-scale with achievable resolutions below one Ångstrom. However, these are only two-dimensional (2D) projections of complex three-dimensional (3D) structures. 3D morphology and composition are critical to determine the function of nano-structures used across many fields, such as energy, catalysis, electronics, and quantum materials. The success of electron tomography has fueled rapid innovation in quantitative, sub-nanoscale 3D analysis in electron microscopy that include recent achievements of atomic resolution and methods to determine 3D structure from few (even a single) projection image.

P04 - Correlative Microscopy of Rapidly Solidified Microstructures in Additively Manufactured Builds

Metals, ceramics, concrete, and polymers are being used in diverse additive manufacturing (AM) applications. Parts and components processed through these incremental layer-by-layer manufacturing techniques have microstructures that depend on a variety of factors like directed power source (e.g. laser or electron beam, arc-discharge), processing parameters (dwell, shape/contour region), choice of feedstock materials and post fabrication treatments. With modeling guided experimental control, site specific material properties can be engineered in AM parts because control of microstructure in pre-defined areas can be achieved. Contributions are invited on research of microstructures in additively manufactured components at multiple length scales through multi-modal microscopy/microanalysis characterization techniques, including OM, FESEM/EBSD/EDS/TKD, AEM, STEM, EELS, APT, EPMA and XCT. Correlation of microstructures to process conditions and final component properties are encouraged.

P05 - Microscopy and Microanalysis of Materials under Multiple Environmental Extremes

Future energy systems will expose materials to multiple extreme environments, often simultaneously, such as high temperatures, stress/strain, radiation, and corrosion/oxidation. When applied concurrently, these synergistic interactions can lead to unique material responses not found from sequential application of the same conditions. Understanding the mechanisms of materials' responses to multiple extremes therefore requires advanced characterization/testing, including in-situ analyses of separate and combined stimuli. This symposium will bring together experts in radiation effects, corrosion, mechanical behavior, and advanced microscopy, with an emphasis on the application of latest-generation methods of microscopy, microanalysis, and data analytics to tackle problems in materials under coupled extremes.

We invite submissions from former students and collaborators, as well as researchers working broadly in the area of in situ heating and gas reaction studies, topics of his interest over the past 15 years. Bigelow joined EMSA in 1950 and served in many roles including President in 1969, when the annual meeting was also held in Minneapolis. He taught his electron microscopy course for 35 years at Michigan. The techniques of in situ heating and gas reactions have evolved considerably from the mid 1960s when Bigelow studied the oxidation of Cu single crystal films using a JEOL JEM-6A with a 16-mm cine film camera. In retirement, Bigelow became active in designing specialized equipment for microscopy, and he collaborated into his 90s in pioneering the development of closed-cell gas-reaction techniques that are currently popular in the field. This symposium will feature talks and posters in the general areas of in situ heating and gas reactions (utilizing both closed-cell specimen holders and differentially pumped E-TEM techniques), all for materials science applications.
